Shares of the defunct consumer electronics retailer Tweeter, which once had a store in the Charleston region, got a big jolt Friday after investors mistook it for Twitter.

The mix-up unfolded less than a day after the popular San Francisco-based online messaging service filed plans to sell as much as $1 billion of its stock under the ticker “TWTR.”

Tweeter Home Entertainment Group Inc., which has the symbol “TWTRQ,” skyrocketed as much as 1,800 percent Friday after the U.S. markets opened. The stock topped out at 15 cents, according to Yahoo Finance.

More than 14.4 million shares changed hands before trading was halted at 12:42 p.m., when Tweeter was down to a nickel. Over the past year, the daily average volume was about 29,000, according to FactSet.

The Financial Industry Regulatory Authority stepped in after determining “an extraordinary event has occurred or is ongoing that has had a material effect on the market” for the stock. It also cited a misunderstanding related to the “possible initial public offering of an unrelated security.”
